"Solid-state batteries, which show the merits of high energy density, large-scale manufacturability and improved safety, are recognized as the leading candidates for the next generation energy storage systems. As most of the applications involve temperature-dependent performances, the thermal effects may have profound influences on achieving practically accessible solid-state batteries. This review systematically summarizes the thermal effects at different temperature ranges and the corresponding strategies to minimize the impact of such effects in solid-state lithium batteries. The review also discusses thermal effects in non-lithium based solid-state batteries, including temperature-dependent performances of different types of non-lithium based solid-state batteries. The perspective for the future development of different approaches in mitigating the impact of thermal effects in solid-state batteries is also presented at the end of the review."

One potential industrial solution to decarbonisation is thermal energy storage. This technology stores energy in the form of heat with output temperatures up to 1300 °C, making it highly suitable for industrial applications. https://lnkd.in/eUka4nMb

Excited to share a new publication led by Doo Hyun Chung and Edward Graham, in collaboration with Landon Schofield, Prof. Benjamin Paren and Prof. Yang Shao-Horn, on the design space for cost effective hydrogen production via PEM electrolyzers. The paper uses a physics-based PEM electrolyzer model coupled with design and scheduling economic optimization model to explore the drivers of low-cost electrolytic H2. Highlights include: - Dynamic operation reduces LCOH vs. static operation, with increasing maximum current density increasing cost savings, particularly in future renewables dominant grid scenarios - Differential pressure operation upto 30 bar H2 becomes more cost-effective under future grid and capex scenarios - Achieving $1/kg remains a challenging target for available capex projections and would require further reductions in capex and electricity supply - Grid-electricity based hydrogen on its own will not be eligible for 45V without additional measures either at the grid level or producer-level https://lnkd.in/ec29vHSP

What do bricks, hand warmer gel, air, and salt have in common? Well, according to researchers, they are energy sources! There's more: They can be used in place of conventional lithium batteries to store energy as heat because they hold warmth for a long time. What do you think about this groundbreaking discovery?

Credit to Roger Harrabin and The Guardian for making important knowledge and insight available to the public, in times when the noise is significant, through sincere and deep research. Enjoy the reading, served on a silver platter! "Think of battery ingredients and lithium, cadmium and nickel come to mind. Now think again." "Heat storage is coming up the agenda: last month a Lords committee urged the government to take energy storage more seriously, and this month a conference run by the Institution of Mechanical Engineers (IMechE) will hear the case for thermal batteries. One featured technology at the meeting will be the Heatcube, developed by a Norwegian firm, Kyoto Group." "Unlike much sought-after electrical battery components, salt is widely dispersed, easily extracted and able to store heat with minimal degradation or toxic by-products." "Dr Robert Barthorpe from Sheffield University, who studies storage options, says: “Molten salt is going to be an important part of the energy mix. It’s a fantastic technology, offering high temperatures at industrial scale.” https://lnkd.in/dmSd9Mjz

Hello everyone, Let us take a moment to discuss energy. Recently, energy topics relating to climate change, carbon capture, and hydrogen production have attracted sizable attention. One standout class of porous materials, known as metal-organic frameworks (MOFs), shows exceptional promise in addressing major energy challenges. Another innovative approach to energy generation is converting waste heat into electricity. Given that waste heat is a common byproduct in numerous processes, utilizing it as a renewable energy source offers a practical solution to our energy challenges. I am excited to share our latest research on thermoelectric generation using a MOF-based material. The most effective thermoelectric materials should possess high electrical conductivity, low thermal conductivity, and high thermopower. These properties are interdependent; altering one can impact the others. Our study demonstrates how we have managed to increase the electrical conductivity of a highly insulative MOF, minimize its thermal conductivity, and maintain its porosity. The outcome is a thermoelectric material capable of generating millivolt-level electricity. I am grateful to my co-authors: Dr Brendan Dyett, Dr Billy Murdoch, Dr Al Jumlat Ahmed, Prof. Gary Rosengarten, Prof. Rachel Caruso for their immense contributions to the project. To Dr Cara Doherty and Prof. Xavier Mulet,  thank you for giving me the opportunity to work on this project. For more details, please see https://lnkd.in/gnqHqn9M
